Pushrod - 5/16 .080 6.750 Long

The Pushrod - 5/16 .080 6.750 Long is a precision valve train component engineered for high-performance small-block and mid-sized engine builds. This hardened steel pushrod connects the valve lifter to the rocker arm, transmitting precise valve actuation commands from the camshaft through the entire valvetrain. Whether you're assembling a street engine, bracket racer, or classic car restoration, selecting the correct pushrod diameter, wall thickness, and length is critical to achieving reliable valve timing and preventing catastrophic lifter or rocker arm failure.

Trend Performance Products manufactures this pushrod with a 5/16-inch diameter and .080-inch wall thickness, balancing strength and light weight for responsive valve action and reduced inertia. The 6.750-inch length is designed to maintain precise pushrod-to-rocker geometry across common small-block applications, ensuring consistent valve lift and duration without deflection under aggressive cam profiles. The hardened steel construction resists galling and wear at both the lifter and rocker arm ball seats, critical when running solid lifters, high-RPM cams, or unconventional valve covers that demand exact stack height.

Mechanics and engine builders favor this pushrod length and diameter for Chevrolet small-blocks, Ford 289–302 platforms, and comparable domestic V8 architectures using standard or aftermarket cylinder heads with factory-pattern rocker studs. Verify your specific engine's pushrod length requirement—incorrect length causes rocker arm preload issues, valve lash problems, or complete valvetrain bind. Installation requires careful measurement from lifter cup to rocker arm ball, and checking rocker geometry under load before final engine assembly to guarantee optimal performance and longevity.
